Verastream Transaction Integrator

The architecture of Verastream Transaction Integrator (VTI) is centered around three main components: the VTI Server, the VTI Designer, and the VTI Runtime. The VTI Server is the core component, providing the runtime environment for executing integration models. The VTI Designer is a graphical tool used to create and configure these models, which define the interactions with CICS and IMS applications.

The VTI Runtime is responsible for executing the models created in the Designer, handling data mapping, and providing access to legacy data via REST or SOAP APIs. Communication between components occurs primarily through network protocols such as HTTP and HTTPS. The VTI Server uses configuration files, typically XML-based, to define connections to legacy systems, security policies, and other operational parameters.

The VTI Designer generates these configuration files based on the models created by the user. The system does not use a dedicated database for storing transactional data; instead, it directly interacts with the legacy systems. Network requirements include open ports for HTTP/HTTPS communication.
